H I INVENTOR. Jan/15s A. (m 42y ATTORNEY United States Patent 3,145,687 JET TYPE MOTOR James A. Conley, lweadville, Pa, assiguor to Revley Corporatien, Meadville, Pa., a corporation of lennsylvania Filed Apr. 26, 1962-, Ser. No. 190,273 3 Claims. (Cl. 115-12) This invention relates to boats and, more particularly, to outboard motor boats.

Boats of the ordinary propeller type usually have their propellers extending down below the bottom of the boat. In this position, they are vulnerable to damage by rocks and other obstructions which the bottom of the boat passes over. Jet type boats such as shown in Patent No. 2,998,701 have the inlet to the jet disposed below the bottom of the boat where it can be damaged. The jet is so positioned in the present invention that its jet action will be effective even when the discharge nozzle is out of the water.

The present invention discloses an outboard motor boat with a jet propeller arrangement with a tube. The propeller is housed inside the tube and the inlet to the tube is disposed flush with or above the bottom of the boat where it cannot be easily damaged.

An improved bracket is also provided for supporting the motor or the transom of the boat in such a manner that the jet can be tilted to change the angle of attack of the jet for maximum efficiency.

It is, accordingly, an object of the present invention to provide an improved bracket for attaching the outboard motor to the back of a boat.

Another object of the invention is to provide an improved combination bracket on an outboard motor wherein the bracket may be adjusted to change the angle of attack of the motor to the water.

A further object of the invention is to provide a motor for an outboard boat which is simple in construction, economical to manufacture, and simple and efficient in operation.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts, hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. 1 is a side view in section of a motor according to the invention supported on the back of a boat;

FIG. 2 is a front view of the bracket;

FIG. 3 is a rear view of the bracket and motor supported on the boat; and

FIG. 4 is a side view of the bracket.

Now with more specific reference to the drawing, a motor is shown attached to a boat 11 by means of a bracket 14. The motor 10 extends downwardly at 13 with a suitable propeller shaft and the like and is attached to an impeller supported in a housing 16. The housing has a jet nozzle 15 attached thereto which is suitable to run below the surface of the water at 12.

The motor 16 can be of any suitable type of outboard motor and it can have a suitable propeller shaft extending down through the member 13 and attached to the propeller housed in the housing 16. The housing 16 is generally cylindrical in cross section. It acts as a channel to force water from its inlet 29 which is in a horizontal plane to its outlet.

The bracket 14 has a groove 17 defined by an upwardly extending leg 18. The upwardly extending leg 18 and a portion 19 spaced therefrom define the groove 17 therebetween which receives the top of the boat transom. Clamping lugs 20 may be tightened to clamp the bracket 14 to the boat so that the leg 18 lies along the transom of the boat 11 and the lugs 20 lock the leg 18 thereto.

A bracket 30 has an arm 22 which extends downwardly therefrom. This arm is pivoted to the leg 18 at 23 and have a rearwardly extending fin 24 integral therewith. The fin 24 forms a stabilizer on the rear end of the boat to prevent water from flowing through an opening 25. The motor is pivotally supported on the bracket fit) at 26 so that the motor can be turned from side to side to steer the boat.

When the pin 23 is in position, a pin 36 can be removed and be replaced selectively in one of the holes 2'7 so that the motor can be tilted forward or backward and swung around the pin 23 to change the angle of attack of the inlet 29 to the channel.

It will be seen that when the boat is running through the water, the inlet 29 will be flush with or above the surface of the bottom of the boat and the jet nozzle 15 will discharge water either into the water or into the air above the water, in either case giving the boat a forward thrust.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A jet outboard motor and means for installing it comprising: a first bracket having spaced legs adapted to rest against the outside of the transom of a boat,

clamping means for clamping said legs to said transom,

a second bracket having a downwardly extending arm adapted to extend substantially to the bottom of said transom,

pivot means attaching an outboard motor to said arm,

said arm being pivotally atached to said legs adjacent the bottom of said transom,

a plurality of spaced holes in the top of said second bracket,

a hole in said first bracket adapted to be selectively aligned with said holes in said second bracket, a pin extending through said hole in said first bracket and one of said holes in said second bracket,

a channel in the bottom of said motor, said channel having an inlet being adapted to be disposed in a plane substantially parallel with the bottom of said boat, a jet discharge from said channel,

said inlet remaining adjacent the bottom of said transom irrespective of the said hole in said second bracket in which said pin is received.

2. he motor and clamp recited in claim 1 wherein said jet discharge is disposed above the plane of the bottom of said boat.

3. The motor and clamp recited in claim 2 wherein said pivot means comprises a fin on said arm and an opening in the front of said motor, said fin being disposed in said opening.
